Between a Rock and a Hard Place - Aron Ralston [172]
cornice: A snow feature usually found on summits and ridges where wind blows and compacts the snow into an overhanging bulge, like a frozen wave curl.
couloir: A funnel- or hourglass-shaped snow-filled gully, usually exposed to rock and ice falling into it.
crampons: Metal spikes, often arranged ten or twelve per foot on boot-length metal platforms that are strapped to mountaineering boots for climbing snow and ice.
daisy chain: A six-foot-long sewed loop of half-inch-wide Spectra webbing that is stitched to itself every five inches along its length, creating a series of load-bearing fabric links in a “chain” of webbing. Typically, at exposed rappel anchor sites, with one end of the daisy chain hitched to his climbing harness, a climber clips a carabiner through one of the links to a solid anchor to prevent a fall while working near the edge.
downclimbing: Descending steep terrain using climbing techniques, as opposed to rappelling or using anchors.
DPS: Department of Public Safety; in Utah, the DPS oversees the state highway patrol.
ECSO: Emery County sheriff’s office.
ICS: Incident Command System, the command structure and guidelines used by most government agencies and search-and-rescue teams to manage large-scale emergency operations.
Lexan: Trade name of a type of hard plastic, used in some outdoor recreation water bottles.
mixed: Combination of ice, snow, and rock terrain; also mixed climbing, climbing on mixed terrain, using crampons and ice tools on rock.
Nalgene: Brand name of a company that makes outdoor recreation water bottles.
NPS: National Park Service, an agency within the Department of the Interior that administers national monument and park lands.
progress-capture loop: A knot, such as a Prusik knot, used in lifting systems to hold the load in place while the haul system is reset for a subsequent lift.
Prusik knot: A special friction knot useful for ratcheting operations such as ascending a rope or in pulley systems. When loose, the knot can be slid up a rope but locks when tightened under downward force.
randonée (also alpine touring, or A/T): Backcountry skiing equipment similar to downhill ski equipment but with rear binding components that allow the boot heel to lift for uphill travel, then lock the heel down in ski descent mode. Unlike telemark skiing boots, A/T boots can be used with most crampons.
rappelling: Descending a cliff using a rope and a special friction device.
rappel ring (also rap ring): A welded aluminum ring that links a climbing rope to an anchor for rappelling, allowing a climber to pull the rope down from the anchor more freely, once the rappel is completed.
SAR: Search and rescue.
Spectra: Trade name for a type of synthetic fiber used in climbing ropes and webbing, stronger for its weight than traditional fibers.
stemming: See “Chimneying.”
telemark: Backcountry skiing equipment with a single free-heel mode that allows for both uphill travel and downhill skiing; named for a region in Norway. Downhill technique on telemark gear uses an alternating dropped-knee stance that advances one ski in front of the other to execute a turn. Telemark boots have a toe baffle that flexes, which is necessary for the telemark ski stance, but which makes them incompatible with most crampons.
travertine: A type of rock formed by water with high concentrations of lime that are deposited wherever the stream flows or splashes. As the creek changes course or water levels drop, lime residue solidifies into travertine and changes from white to burgundy as other minerals in the accretion, notably iron, oxidize and turn red.
webbing: Flat or tubular strips of closely woven high-strength fabric, useful for building climbing anchors. Usually used in three-quarter, one-inch, and one-and-a-half-inch widths.
yarding: In climbing, to pull hard on a handhold.
